PALO ALTO, Calif., May 23, 2001 — Informatica Corporation (NASDAQ: INFA), the leading provider of eBusiness analytic solutions, today announced that eBay’s (NASDAQ: EBAY) successful implementation of Informatica PowerCenter data integration software has received the prestigious “Best Practices in Data Warehousing” award from The Data Warehousing Institute (TDWI).  eBay’s award-winning implementation of Informatica PowerCenter has helped the company better understand market dynamics between buyers and sellers, improve customer relationships and increase bottom-line revenue.  eBay was honored by TDWI in the E-Intelligence & Clickstream Data Warehouse category.

Nominations were judged by a panel of experts, including practitioners, consultants, industry analysts, journalists, Journal of Data Warehousing editors, TDWI Fellows and TDWI management. The winners were selected by demonstrating that their data warehouse and business intelligence projects were truly innovative solutions to problems commonly faced by data warehousing practitioners and were practices that could be followed by others.

According to TDWI, eBay’s implementation won by clearly demonstrating: (1) impact and value to end users, (2) best practices other companies can adopt, (3) innovative strategies, technologies, architectures or processes used to design its analytic environment and (4) the close alignment between business and IT processes.

“The competition for the Best Practices Awards was exceptionally strong this year,” said Ellen Hobbs, general manager of TDWI. “As always, the quality of the applications was first rate, but several nominations distinguished themselves as true best practices that others can learn from and utilize in their own data warehousing and business intelligence implementations.”

 “TDWI’s recognition of an Informatica customer for the fifth consecutive year demonstrates our ability to deliver powerful, innovative analytic solutions to today’s leading companies,” said Diaz Nesamoney, president and COO of Informatica. “We’re proud our solutions help customers and partners achieve high levels of business success, and congratulate eBay on its well-deserved win.”

eBay and other Best Practices award winners will present their winning nominations at TDWI’s World Conference — Summer 2001 in Anaheim, California on August 12-17, 2001.
